PURPOSE:To quicken the arrangement of each coil and to prevent the deflection of a base material by inserting plural base coils into a core shaft member, making the coils horizontally movable, and then successively uncoiling the coils while pressing the coils with a press roller. CONSTITUTION:A wire is passed through the core hole 23a of a base coil 23 for plural spacers to suspend the coils, and the coils are placed on a couple of pipes 40 of the spacer supply device and the bottom of a box 30. The core shaft member 29 is then inserted into the core hole 23a, and both ends of the member 29 are engaged into a bearing 31. The bearing 31 is raised by a handle 33, and separated from the pipes 40 to make the coil 23 rotatable around the member 29. The coil 23 is pressed from the upper part by the press roller 38 through an arm 39, and the spacer base material 20 is uncoiled by rotating the coil 23. ln this case, the torsion and meandering of the base material 20 are prevented. In addition, the box 30 is horizontally moved on a rail 36 by a handle 37, hence the base material 20 is successively positioned on a supply line, and the work is quickened.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention uses aluminum (Aρ) or A to rewind a tight coil into a loose coil in order to improve heat conduction during the quenching process of alloy coils, etc. The present invention relates to a supply device for loose coil spacers that are inserted between coil plate materials.

[Prior Art] In the A, fl or A°C gold alloy quenching process, the tile coil of the strip material is once unwound, and usually a pair of spacers are continuously supplied to both ends of the strip material in the width direction. This strip material is wound up again while inserting a spacer between the inner diameter side strip material and the outer diameter side strip material. As a result, Aff
A spacer is interposed between the L or Aρ alloy strips to obtain a loose coil with a gap. The spacer material is attached to the spacer supply device as a narrow thin plate coil with a width of 10 to 25+++n+ and a plate thickness of 0.5 to 1. The material unwound from this coil is placed in a molding machine. After forming irregularities with a height of 5 to 8 mm, the material is supplied to a loose coil winding device installed on the same line.

The length of the spacer material is substantially the same as the length of the A1 or A1 alloy strip material, and the unit weight of this spacer coil is 30 to 40 kg.

[Problems to be Solved by the Invention] However, these conventional spacer supply devices have a problem in that it takes time to set up the coils. That is, in the coil setup work, various operations are required, such as centering the line and changing the position of chi 1 after suspending the spacer coil with a crane and mounting it on the reel. Therefore, for example, it takes 15 to 20 minutes for two people, a crane operator and a safety worker, to set up the coil. In this way, the coil setup work becomes a factor that hinders productivity improvement.

In addition, the box type device in particular has disadvantages in that the coil is easily scratched and the spacer material is not delivered smoothly and is likely to be wavy.

The present invention has been made in view of such problems, and includes:
It is an object of the present invention to provide a supply device for a spacer for a loose coil, which can speed up setup work such as setting a spacer coil and centering a line, thereby improving productivity.

Means for Solving 1 Problem] A loose coil spacer supply device according to the present invention includes a core shaft member that supports a plurality of spacer raw material coils by inserting the core holes thereof, and a core shaft member that supports the core shaft member by lifting and lowering the core shaft member. It has an elevating device for driving, a lateral moving device for moving in the axial direction a core shaft member that supports the spacer material coil through its core hole, and a presser roller that rolls on the outer surface of the spacer material coil. It is characterized by

1 Effect] In the present invention, by inserting the core shaft member into the core hole of a plurality of spacer material coils, a plurality of the material coils are collectively set in the spacer supply device.

Then, the core shaft member is raised by the lifting device, and the plurality of raw material coils are supported by the core shaft member. Next, the core shaft member is moved in the axial direction by a lateral movement device, and the position of the coil supported by the core shaft member is moved in the axial direction of the core shaft member, thereby forming the coil into an uneven shape. Align to a given supply line. Then, the spacer material is unwound from the coil and supplied to the molding machine. In this case, since the presser roller or the outer surface of the spacer material coil is rolling, for example, at the unwinding point of this coil, the hoop of the coil will not bend even if the line speed is accelerated or decelerated. do not have. Moreover, the setup for the next coil is completed by simply arranging the next coil on a predetermined supply line using the lateral movement device.

In this way, you can set multiple coils at once,
Spacer materials can be successively supplied to the molding machine simply by moving these coils in the axial direction of the core shaft.

[Examples] Examples of the present invention will be specifically described below with reference to the accompanying drawings.

FIG. 1 is a front view showing a spacer supply device according to an embodiment of the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a front view showing a loose coil manufacturing line in which this supply device is incorporated. be. As shown in FIG. 3, the spacer material 20 unwound from the spacer supply device 1°O according to the present embodiment is sent to the spacer molding machine]01, and the spacer material 20 is sent to the spacer molding machine ]-01 to adjust the height, e.g. A spacer 21 having an unevenness of 5 to 8 mm is formed.

This spacer 21 is supplied to a loose coil winding device 102. On the other hand, Aρ or A to be heat treated, ! Tie 1 in which a strip material of two alloys is tightly wound - a strip material 22 unwound from a strip material supplying device 103 attached to a coil;
is fed to the winding device 1.02. In this winding device 102, the spacer 2]- is inserted between the inner diameter side strip material 22 and the outer diameter side strip material 22, and the strip material 2
2 onto the reel. This results in a loose coil.

Next, the spacer supply device 100 will be explained in detail. The coil box 30 has a box shape with an open front and upper part and a notch in the upper front part of the side wall, and has a six-piece structure, with six spacer materials in each coil box 30. The coils 23 are arranged separated by partitions 30a. As shown in FIG. 2, two coil boxes 30 are provided in the spacer supply device 100.

Bearings 31 are disposed on both sides of each coil box 30 so as to be movable up and down by a lifting device 32 . A shaft core member 29 that is inserted through the core hole 23a of the coil 23 is fitted into this bearing portion 31-. Furthermore, by manually rotating the lifting handle 33, the driving end of the lifting device 32 moves up and down, thereby driving the bearing portion 31 up and down.

Bearings 34 are provided at the four corners of the bottom of each coil box 30, and wheels 35 are rotatably supported by the bearings 34. A pair of rails 36 extending in a direction perpendicular to the supply line of the spacer material 20 is laid on the factory floor. Then, the car 1fiii 35 is engaged with the rail 36, so that the coil hox 30 is moved along the rail 36, that is, the spacer material 20
It can be moved laterally in the direction perpendicular to the supply line.

The horizontal movement of this coil box 30 is performed using the horizontal movement handle 3.
It is driven by rotating 7.

Three arms are swingably attached to the head of each coil box 30, and a presser roller 38 is rotatably installed at the tips of the three arms.

As a result, the presser roller 38 is transferred to the outer peripheral surface of the material coil 23 at the unwinding position of the material 20, and the material coil 23
This is to prevent the material 20 from bending when the rotational speed of the material changes.

A pair of pipes 40 are disposed at the bottom of the coil box 30 with their longitudinal directions aligned with the opposing directions of the pair of bearings 31 to prevent rolling when the coil 23 is housed in the box 30. This is to prevent this and stabilize the coil 23.

The distance between the side walls of the box 30 is set to a length that allows the spacer material 20 to be supplied from the pair of boxes 30 to both ends of the Affl or Aρ gold alloy strip material 22 at its minimum width. do. In addition, the interval between the partition plates 30a in each box 30 is approximately twice the maximum width of each spacer material 20, and the degree of freedom with respect to the inclination angle of the surface of the material coil 23 and when this coil 23 is attached I am trying to make sure that I have enough money.

Note that the side wall and bottom of the box 30 may be made of nylon or the like to prevent the coil 23 from being scratched. However, since this is not a spacer white product and slight scratches are not a problem, such measures are not necessarily necessary. Further, in order to reduce the impact when the coil is stored, the bottom of the hook 30 and the pipe 40 may be covered with a comb.

Further, the lifting and lowering of the bearing portion 31 and the lateral movement of the box 30 may be performed by thin link drive such as hydraulic pressure or pneumatic pressure, or electric drive by a motor; however, the box 30 and the coil 23
Since it is relatively light in weight, it can be done manually as described above.

It is preferable that the presser roller 38 is rubber laminated. This pressing roller 38 presses the outer periphery of the coil 23 with its own weight, and prevents the coil 23 from being twisted or wavy when unwinding, and also reduces the loop amount of the coil when the coil rotation is decelerated and stopped. let Further, the presser roller 38 also contributes to preventing the material 20 unwound from the coil 23 from twisting and meandering. This pressing roller 38 and arm 39 are removably attached to the box 30. As a result, when installing the coil 23 in the box 30, this presser roller 38
The holding roller 38 and the arm 39 can be removed so that they do not interfere with the installation work of the coil 23, and when the coil 23 that sends out the spacer material 20 is changed to the next one. The coils 23 are reattached to the next coil 23, and one presser roller 38 is used as a presser for the six coils 23. Note that this presser roller 38 can be attached to the position where each coil 23 is disposed so as to be openable and closable, as long as it does not interfere with the work of attaching the coil 23.

Next, the operation of the spacer supply device configured as described above will be explained. First, as shown in FIG. 4, a wire (
or a rope) 52, this wire 52 is locked to the hanging bar 51, and the six coils 23 are suspended from the hanging bar 51.

Then, this hanging bar 51 is lifted by the hook 50 of the crane, and the coil 2 is lifted by the crane's traversing and running.
3 from the loading location to the spacer supply device.

Note that the conveyance of this coil 23 is as shown in FIG.
The holding bar 53 may be inserted into the core hole 23a of the coil 23, and both ends of the holding bar 53 may be supported by hooks 50 of a crane.

Then, by lowering the hook 50 of the crane with the presser roller 38 and arm 39 removed, the coil 23 is loaded into the box 3o from the upper front part, and the coil 23 is inserted into the box 3o from the top and the bottom of the box 30. Place it on. As a result, the coil 2 is placed between the partition plates 30a of the box 30.
3 is installed. Next, the core shaft member 29 is attached to each coil 23.
is inserted into the core hole 23a, and both ends of the two core shaft members are engaged in the bearing portion 31. And the handle 33
is rotated to raise the bearing part 31 by the lifting device 32, and the core shaft member 29 is raised. Then, each coil 2
3 is lifted up by the core shaft member 29 inserted through the core hole 23a and separated from the pipe 40. After that, coil 23
is supported by the core shaft member 29 through its core hole 23a, and can rotate around this core shaft member 29.

Next, the presser roller 38 and arm 39 are placed in the box 30.
The presser roller 38 is placed on the outer peripheral surface of the coil 23. Such a coil 23 mounting operation is performed for each pair of boxes 30.

Thereafter, each box 30 is moved laterally along the rail 36 by rotating the handle 37. As a result, among the six coils 23 for each box, the coil 23 from which the spacer material 20 is to be dispensed is transferred to the feeding line of the spacer material 20 and spacer 21 that passes through the forming machine 101 and reaches the loose coil winding device 102. position it above.

Next, the raw material 20 is unwound from each coil 23 in the pair of boxes 30 and supplied to the molding machine 101. In this case, since the presser roller 38 transfers to the outer circumferential surface of the coil 23 by its own weight and presses the material 20 on the outer circumference of the coil 23, even when the coil rotation speed decreases such as when decelerating or stopping. The spacer material 20 does not bend.

Further, the press roller 38 prevents the spacer material 20 from twisting or meandering.

After that, when the spacer material 2o has been discharged from the coil 23, the handle 37 is rotated to move the box 30 laterally, position the adjacent coil 23 on a predetermined supply line, and then release the spacer material 2o from the adjacent coil 23. Material 20
pay out. In this way, the spacer material 20 is sequentially supplied from the adjacent coils 23.

As described above, in this embodiment, six coils 23 are set at the same time, and while each coil 23 is moved laterally, the spacer material 20 is sequentially unwound and delivered.

Therefore, in this embodiment, among the six coils,
As for one piece, 15 to 20
minute setup time is required, or for the other five items,
It only takes 2 to 3 minutes for one person to do it. Therefore, overall, the coil setup work can be speeded up and the work can be carried out with fewer workers.

Note that the present invention is not limited to the above embodiments.

For example, the above embodiment relates to a spacer supply device for a loose coil of Aρ or A4 alloy strip material.
The loose coil can be made of various materials such as iron-based materials.

[Effects of the Invention] According to the present invention, a plurality of coils are collectively supported by a core shaft member, the spacer material is unwound from the coil while being pressed by a presser roller, and the plurality of coils are unwound by a lateral movement device. Since the coils are placed one after another on a predetermined supply line, the setup work for each coil is speeded up, the resistance during unwinding is reduced, and the material does not bend when decelerating or stopping. suppressed.
